1 | Resizable Endpoint Boundary (x4) | Defines the four corners of the rectangular region. Click on an end-point boundary to resize the ROI from one of its corners.
2 | Mask | Defines the area of the image that will not undergo image analysis. The mask can be moved and resized within the ROI. A total of 99 masks may be added to a ROI.
